well for anyone that lives around the plano,garland,richardson,allen TX areas fair warning that at the begining of this year 30 Pro Laser III were purchased and now majority, (about 70%) of the police are solely using LIDAR. I go past so many cruisers now that dont even use there radar while driving. Within the past 5 days of having my Pro-73 i have been lasered 6 TIMES, yes 6 times throughout 3 different counties. This was all used in pretty residential areas too, only one happened on the Highway. So fair warning... I would get a jammer but basically they zap you at like 200ft and step out into the road so would a jammer even jam when they are that close to you? They hide very good.
